/proc/ioports from Abit KN9

Well, first things first; I'm withdrawing the patch because I didn't check I'd
removed the custom DSDT which disabled the offending IO port write first...

So, the patch doesn't work and can be safely ignored (feel free to jump off the
CC list if this is now no longer relevant to you).

However, we are still stuck with the problem that Linus' suspend commit in
question is the cause here of a wedged suspend (as confirmed by Arthur, the
original bug submitter).

So, now that I've wasted everyone's time by CC'ing you all for a patch that
doesn't work - what do we need to do to try and hunt down the real cause of why
the 0x142E port write wedges suspend?

Attached is the output of /proc/ioports

As already noted here though, my first assumption was that PNPACPI was the
culprit here - port 0x142E is in a range reserved by PNPACPI - but booting with
pnpacpi=off has no effect on suspend (the range is no longer reserved, but
suspend still wedges).
